I have a Coastal Scents palette (88 colors) and I love the thing to bits.
The thing to be aware of with palettes like that is that on their own the colors aren't very pigmented and fade quickly. You need a primer to utilize them well. When you do, though, the colors really POP. How long they last will depend on the primer that you use. I'd recommend Urban Decay's eye primer (the one that comes in a tube with a wand) or the green-ish toned concealer from BitchSlap Cosmetics. I'm using the eye primer from Mac right now and I'd say that it's quality is between the two previously mentioned.
